ARC: switch to generic ENTRY/END assembler annotations

ARC: switch to generic ENTRY/END assembler annotations

commit ec7ac6afd07b2d958aab9dfc0a686300b856922a upstream.

With commit 9df62f054406 "arch: use ASM_NL instead of ';'" the generic
macros can handle the arch specific newline quirk. Hence we can get rid
of ARC asm macros and use the "C" style macros.
